Exercise stress testing is crucial for diagnosing coronary artery disease. Optimal methodology involves a 8-12 minute test, small workload increases, and symptom-limited assessments for accurate diagnosis and prognosis.

Area of Science:

  • Cardiology
  • Exercise Physiology

Context:

  • Exercise testing is a key non-invasive diagnostic tool for coronary artery disease (CAD).
  • Significant advancements have improved exercise test methodology and interpretation.

Purpose:

  • To outline optimal methodologies and interpretation strategies for exercise testing in CAD patients.
  • To highlight key parameters for accurate diagnosis and prognosis.

Summary:

  • Optimal exercise testing involves a 8-12 minute duration with gradual workload increases (ramp protocol preferred).
  • Testing should be symptom-limited, with submaximal testing reserved for post-myocardial infarction cases.
  • Interpretation relies on double product, clinical/hemodynamic responses, and ST-segment changes, with ST depression being a critical diagnostic marker.
